What's up in
Once missing in action, middleweight black holes have finally been detected. Now researchers are trying to figure out how they grow from small ones.
Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls.
Physicists have reached a long-sought goal. The catch is that their room-temperature superconductor requires crushing pressures to keep from falling apart.
The physicist Jeff Gore tests theories about microbe communities experimentally and finds new rules governing ecological stability.
Roger Penrose, Reinhard Genzel and Andrea Ghez were awarded the Nobel Prize in Physics for their studies of black holes.
